Abstract: Unit for packaging and palletizing rolls of paper comprising a bagging and/or forming machine adapted to sort packages of said rolls into batches or to bag said sorted loose packages in a plastic bag, and a palletizing station comprising at lease one manipulator provided with grippers to handle loose packages of delivered products from said bagging and/or forming machine. The products are conveyed to said palletizing station with a predetermined stepped sequence and spaced from one another in at least one row on a conveyer element, wherein said at least one robot and said bagging and/or forming machine are interconnected and are programmed respectively to sort said products in batches of different forms and dimensions according to a sequence which is continuously variable to form a layer of a pallet with different batches of products adjacent to and engaged with one another.

Abstract: A method and system for packaging rolls of products, in particular rolls of toilet and/or kitchen paper, in which a wrapping sheet is wrapped in a “U” shape around a group of products so that its two end flaps project from the group, each of the end flaps then being folded in an “L” shape so that one portion adheres to the group and the remaining end portion extends transversally to the group and adheres, at the point where they meet, to the end portion of the other flap; the flaps then being sealed to one another at their end portions to form a tubular wrapper.

Abstract: A package of rolls obtained by a wrapping machine includes: a group of rolls composed of at least three layers of rolls, situated one over another; a sheet shaped in tubular form for wrapping the group of rolls, with the relative longitudinal edges overlapped and heat-welded, and with the wings of each head of the tubular sheet being folded against the rolls and then stabilized by heat-welding.
